Thanks for the replies everyone. I guess Python just doesn't have a "declare-variable-as-global-for-whole-module" feature.
(I don't generally have problems with variable overlap because I'm very careful with naming my global variables.) (I just remembered though-- for some reason, list-type variables' individual values/items can be easily accessed throughout the whole module even if: it was just "global"ed once inside the function it was created.) But I just wish I could create variables (of ANY TYPE) which are universally acknowledged by the WHOLE module. Many of my variables' names are re-stating the exact value they hold, so I rarely have any confliction with names: filename_of_current_level = 'desert.txt'' Font__New_Times_Roman_size_20 = ... pi_divided_by_180 = math.pi() / 180 etc. The names are just according to what values they hold which-- are all unique anyways! And when the number of variables start reaching the hundreds, it just gets really crazy with "global this global that" ALL OVER my code, again and again . . . : ( I have to keep remembering to global every other variable in any function that uses my main game variables. If I use dictionaries, I must type: "d['whatever']" for ALL my game variables!!! Same with using classes-- "c.whatever" It's like "pygame.draw.line()" instead of just: "DRAW_LINE()" or like: "random.random()" instead of just: "RANDOM_NUMBER_BETWEEN_0_AND_1()" "Pygame dot draw dot line" (It sounds so lame too) Arrg!! It's like driving me crazy! . . . sigh . . . Sorry guys, I'm just feeling very frustrated with all these crazy programming conventions. I think I need to take a break from programming to help me cool off . . . By far Python and Pygame are the easiest game development tools I know so-- I have no other choice-- Redundant "global"s wreaking havoc on every corner of my program will have to do . . . Anyways, Sorry about my previous posts, sometimes when I get too involved in programming I get a little short tempered-- somehow. . (By the way, thanks for not insulting me even though I deserved it.) I also re-read the messages and found that I had a few inaccuracies and typos as well. I need to remember that people are far more important than just some silly game . . . Thanks again everyone for all your replies. : ) I really appreciate it. ; ) (I'll go get some sun and fresh air hopefully that will help me "cool-off") Matthew N.
